When I want to serve something simple, timeless, and unforgettable, this Moist Kentucky Butter Cake always delivers. It’s rich without being heavy, sweet without being cloying, and irresistibly moist thanks to the golden butter sauce that soaks into every inch of the cake. With its tender crumb and buttery glaze, this Southern staple feels both nostalgic and indulgent.
Whether you’re baking for a potluck, a holiday dessert table, or just a comforting treat to slice after dinner, this cake is the kind that disappears quickly—and earns rave reviews every time.
Why This Cake Works So Well
This is a butter-lover’s dream. It’s not flashy, but it’s deeply satisfying. Here’s what sets it apart:
- Buttery richness in every bite thanks to both a butter-based batter and a poured butter glaze
- Moist and tender crumb that gets better the longer it sits
- No frosting needed – just the simple glaze soaks in and forms a sugary crust on top
- Easy to make with simple pantry staples
- Great for make-ahead – the flavor and texture deepen after a day
This is the kind of cake you cut “just a sliver” of—and then go back for seconds.
Ingredients You’ll Need
For the Cake:
- 2½ cups all-purpose flour
- 2½ tsp baking powder
- ½ tsp salt
- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 1 tsp vanilla extract
- ½ cup buttermilk (or ½ cup milk + 1 tsp lemon juice, mixed and rested for 5 mins)
- ½ cup water
For the Butter Sauce:
- ½ cup unsalted butter
- 1 cup granulated sugar
- ¼ cup water
- 1 tsp vanilla extract
Step-by-Step: How I Make It
1. Prep the Oven and Pan
I preheat the oven to 350°F (175°C) and grease and flour a 9×13-inch baking dish. You want to make sure that cake comes out clean and easy later.
2. Mix the Dry Ingredients
In a medium bowl, I whisk together the flour, baking powder, and salt. Set aside.
3. Cream the Butter and Sugar
In a large mixing bowl, I beat the softened butter and sugar together until pale and fluffy—this takes about 3 minuteswith a hand or stand mixer.
4. Add the Eggs and Vanilla
I add the eggs one at a time, beating well after each one, then stir in the vanilla extract.
5. Combine Wet and Dry
Alternating, I add the dry ingredients and buttermilk/water to the butter mixture, starting and ending with the dry. Mix just until combined. The batter will be thick and silky.
6. Bake the Cake
I pour the batter into the prepared pan and spread it evenly. Then I bake it for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
Make the Butter Sauce
While the cake bakes, I make the butter glaze:
In a saucepan, I melt the butter over medium heat. Then I stir in the sugar and water and bring it to a gentle simmer. I let it bubble for 2–3 minutes, then remove from the heat and stir in the vanilla.
It should be smooth and just slightly thickened—not a syrup, but not watery either.
Pour It While Hot
As soon as the cake comes out of the oven, I poke a few small holes in the top with a skewer or fork. Then I slowly pour the warm butter sauce all over the cake, letting it soak into the crust and crumb.
It will look glossy at first, but give it time—it settles in and forms a delicate sugar crust on top as it cools.
Cool and Serve
I let the cake cool completely in the pan before slicing. The glaze keeps it unbelievably moist, and the flavor deepens the longer it rests.
How I Serve It
This cake is rich on its own, but here are a few ways I like to elevate it:
- With fresh berries and a dollop of whipped cream
- Lightly dusted with powdered sugar
- With a scoop of vanilla ice cream for dessert perfection
- Warm it slightly before serving with coffee for an afternoon pick-me-up
Tips From My Kitchen
- Use real butter for best flavor—this is not the time for margarine.
- Don’t overmix once you add the flour to keep the crumb tender.
- Buttermilk substitute: ½ cup milk + 1 tsp lemon juice or vinegar works great.
- Make it in a bundt pan for a beautiful presentation—just be sure to grease it thoroughly.
- Let it rest overnight—this cake only gets better with time.
FAQs
Q: Can I make this cake ahead of time?
A: Yes! It actually tastes better the next day. Just keep it covered at room temperature.
Q: Can I freeze it?
A: Absolutely. Wrap slices or the whole cake tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw at room temperature.
Q: Can I add flavorings like almond or rum extract?
A: Yes! Try replacing half the vanilla with almond or rum extract for a twist.
Q: Can I reduce the sugar?
A: You can trim the sugar slightly, but don’t cut too much or the texture and glaze will suffer.
